Week 8 - A Very Busy Developmental Stage

An ultrasound done at this stage will show your baby's fluttering heartbeat! He or she is between 0.56 and 0.8 inches from crown to rump, or about the size of a grape. Its liver is churning out large amounts of red blood cells, and will continue to until bone marrow forms and takes over this function.

Week eight marks the beginning of a very busy developmental stage: your baby's face continues to change as the ears, eyes and the tip of the nose appear; the intestines start to form in the umbilical cord; and its teeth begin to develop under the gums.
